Agriculture
According to the Miller textbook which human activity has the greatest harmful environmental impact
Some agriculture systems mimic the functions of natural systems (ex. Rice paddies&wetlands)
Agriculture has negatively affected the environment in all of the following ways except
Alternative energy sources like sunlight and water
All of the following are direct values that forests provide for man EXCEPT
Mowing, prescribed burns, and planting
As a grassland manager you may use the following tools:
Prevent more destructive fires and free valuable nutrients
Benefits of occasional fires
Florida Everglades
Case of ecological restoration and rehab; attempt to redirect water supply
Bottom Trawling
Dragging of weighed net along the bottom to capture species on the ocean floor
Individual Transfer Rights
Fishing rights that can be bought, sold, or leased at market rates are called
Early in mitosis
Foods can be genetically engineered
Forests provide timber and fuelwood
Forests provide ALL of the following ecological services except
Net productivity + cell respiration
Gross primary productivity
Crop Rotation
Growing corn rich grain then switching to legume to help top soil
Alley cropping
Growing crops between rows of trees
Polyculture
Growing many different types of trees or avoiding tilling and pesticides
Legal for use in plants and animals to be consumed and difficult to trace since they may not be labeled
In the US, GMOs are
Fisheries are unsustainable
Increased fish print and bio capacity in breeding pairs
Rachel Carson
Increased public awareness of DDT
Oligotrophic
Lakes that are characterized by high water clarity and low concentrations of dissolved nutrients are classified
A horizon
Layer of soil with must humus and organisms
Erosion and sertication
Major effect of overgrazing
Crown fires
Not an alternative to pesticides
Surface fires
Not threats to forests
Compost
Organic fertilizer made when organisms in soil break down organic matter
Mitigation Banking
Policy allowing destruction of existing wetlands are long as an equal area of the same type of wetland is created and restored
Biodiversity hotspots
Range of different life forms
Integrated Pest Management
Reduction of crop damage to an economically sound level
Effectively locates large schools of fish;
Sonar fishing
Cutting small groups of medium and large sized trees in uneven aged forests
Sustainable use of forests in US would be encouraged by
Physically unstable soils that were exposed to strong winds
The historic dust storm in post settlement Kansas and the plain states were caused by
Wheat rice and corn
Three most popular sources of nutrients
Euthropic
Water is characterized by increased rates of plant growth
Consumer demand and legal for science use
Whaling is controversial

The reintroduction helped to re-establish and sustain biodiversity in Yellowstone
Which of the following WAS a result of the 1996 reintroduction of Gray Wolves to Yellowstone Park?
Too many fish of reproductive age are harvested, making it hard to predict the population size of fisheries
Which of the following best explains why the maximum sustainable yield for ocean fisheries has been exceeded?
